I've written two Lex filks:
Just You Wait, Lexy Luthor! catalogs the various inventive ways FoLCs have killed off Lex in their fics. The HTML version is a bit messed up, in that the lyrics aren't on separate lines, but I'm not sure what I can do about it.
Lex on Life is Lex's philosophy, based on S1, complete with stage directions.
How about Labrat's magnum opus? Masques, I think it was.
